This will assist in managing the vast number of samples that need to be processed during this pandemic. Microbiologists are essential in helping us to treat diseases, many work as biomedical scientists in hospitals and laboratories: testing samples of body tissue, blood and fluids to diagnose infections, monitor treatments or track disease outbreaks. Sometimes bubonic plague progresses to pneumonic plague, when the bacteria reaches the lungs. In their study, the Duke and Duke-NUS researchers set out to determine whether the large swellings that are the signature feature of bubonic plague the swollen lymph nodes, or buboes at the neck, underarms and groins of infected patients result from the pathogen or as an immune response.
